ABSTRACT:
A disc device capable of achieving a slimming down of a tilt adjusting portion is provided. A tilt adjusting member404of a tilt adjusting portion400moves an optical pickup driving portion307along a guide face401ato adjust a light beam303bemitted from an optical pickup303such that an optical axis303cis set perpendicularly to a disc200. Since the tilt adjusting member404is moved in a direction oblique to the guide face401aand a direction perpendicular to the optical pickup driving portion307, an amount of movement of the tilt adjusting member404can be reduced smaller than a necessary amount of tilt adjustment of the optical pickup driving portion307and also a slimming down of the tilt adjusting portion400can be achieved. In this case, since a top end portion of the optical pickup driving portion307is energized by an energizing member405to come into contact with the tilt adjusting member404and the guide face401, this top end portion of the optical pickup driving portion307can be adjusted to come close to and go away from the disc200without wobbling and rattling.
